Oxidative desulfurization of benzothiophene derivatives with cis-dioxomolybdenum(VI) catalyst precursors, under extractive conditions

The study of the activity of a series of heterogeneous cis-dioxomolybdenum(VI) based catalyst precursors for the hydrogen peroxide promoted oxidation of benzothiophene, 2- and 3-methylbenzothiophene, dibenzothiophene and 4,6-dimethyldibenzothiophene, has been carried out. The last, chosen as model substrates of the common sulfurated derivatives of fuels, have been oxidized in the presence of selected imidazolium based ionic liquids, under...
